Abstract
- Objective: To conduct a molecular epidemiological survey on the mitochondrial DNA C1494T mutation in non-syndromic hearing loss patients in Chinese population.<br />Methods: Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) were used to screen the mitochondrial DNA 12S rRNA C1494T mutation in 20 patients with aminoglycoside antibiotic induced hearing loss, 136 sporadic non-syndromic hearing loss patients and 50 probands of pedigrees with non-syndromic hearing loss.<br />Results: The C1494T mutation did not appear in all cases except for the positive control.<br />Conclusion: Incidence of mitochondrial DNA C1494T mutation is much lower than that of mitochondrial DNA A1555G mutation in non-syndromic hearing loss of Chinese population. Mitochondrial DNA C1494T mutation may be a rare variation in non-syndromic hearing loss and is not the main cause of aminoglycoside antibiotic induced-deafness.
